To assist in emulsion removal in the organic phase, 2% (volumer per volume) amount of ethanol was added to disrupt surface tension of the emulsion and clear the organic phase.
The injected volume amount was 1 µL.
This water volume amounts to 9 mcm (SWECO 1997).
The flush volume amounted to 50% of the extraction cell volume.
Factorial design experiments were used in order to optimize the extraction parameters: extraction time, surfactant concentration and surfactant volume:amount of sediment relationship.
MSF concrete cured by steel and polypropylene materials shows much higher pore volume amount than plain and FA concretes for the pore size between 0.1 and 1.0 μm.
The effects of pH, sample volume, amount of 8-HQ and Cu II) and interfering ions on the recoveries of metal ions from standard solutions were monitored using FAAS.
In general, the fermentation process generates twice the volume amount of by-products originating both from the carbohydrate raw material and from the downstream process in the form of a solid sludge (gypsum and organic impurities).
In addition, when the cumulative injection volume amounted to 30 × 104 m3, a third drop in the RPI appeared and a significantly increase appeared in the concentration of polymers in the produced fluids from wells P32-175, P35-174, P35-174, P36-175, and P36-166.
The properties, such as surface area, pore size distribution (PSD), total pore volume, amount and nature of the surface functional groups and surface acidity, of pristine and polarization-treated ACC samples were determined.
